Nutrient Removal

The AquaPASS® Phased Activated Sludge System utilizes time-based process management in a continuous flow configuration. The system provides superior nutrient removal performance in a singular wastewater treatment system. Flexible design and equipment options support a wide range of tank geometries, depth, and footprint limitations, allowing for easy retrofitting of oxidation ditches or other activated sludge processes. Staged aeration provides a unique power savings mode and time-based anoxic intervals promote exceptional nitrate reduction. The flexible nitrogen control system reduces sludge recycling pump requirements, while Phase Separator technology optimizes anaerobic treatment for advanced phosphorus removal and reduces Waste Activated Sludge (WAS) volume 20-50 percent.
